2015 NISSAN PATHFINDER HYBRID engine coolant

The gasoline engine may automatically run in the
following conditions:
●The level of remaining charge in the Li-ion
battery is low. The engine runs to charge the
Li-ion battery and to provide power to drive
the vehicle.
●The temperature of the engine coolant is
low.
●When the A/C is used.
●When L (Low) position is engaged and Over
Drive is off.
●When opening the door.
●When engine hood is opened.
●When applying the brakes.
●Based on driving conditions.
●The shift lever is shifted to the P (Park)
position, the driver’s seat belt is released
and the driver’s side door is then opened.
The hybrid system operates as follows based on
driving conditions and the Li-ion battery charge.The engine is hard to stop during these driving
conditions:
●When the A/C is on and outside tempera-
ture is high/low.
●When repeatedly starting and stopping the
engine.
STARTING AND SLOW SPEED
DRIVING
In some cases, the vehicle can be driven by
electric motor during extremely slow speed
creep, but the engine starts when accelerating or
releasing the brakes.
MEDIUM OR HIGH SPEED DRIVING
The system automatically controls the gasoline
engine and electric motor in order to obtain the
optimum fuel mileage and performance, depend-
ing on the driving situation and available Li-ion
battery charge.
When the remaining battery level is low, the Li-ion
battery is charged by the electric motor that is
driven to generate electric power while the ve-
hicle is driving.
RAPID ACCELERATION
The vehicle is accelerated using both the gaso-
line engine and the electric motor depending on
the available Li-ion battery charge.
DECELERATION AND BRAKING
The Li-ion battery is charged by the electric mo-
tor that changes the energy of the rotating
wheels into electric power. For additional infor-
mation, refer to “Regenerative brake” in this sec-
tion.
STOPPING
The gasoline engine may stop running to save
fuel depending on the available Li-ion battery
charge.

WARNING
●Your brake system may not be working
properly if both the brake warning light
and electronically controlled brake sys-
tem light come on when the hybrid sys-
tem is in READY mode and the parking
brake is not applied. Driving could be
dangerous. If you judge it to be safe,
drive carefully to the nearest service
station for repairs. Otherwise, have your
vehicle towed because driving it could
be dangerous.
Engine oil pressure warning
light
This light warns of low engine oil pressure. If the
light flickers or comes on during normal driving,
pull off the road in a safe area, stop the engine
immediatelyand call a NISSAN dealer or other
authorized repair shop.
The engine oil pressure warning light is not
designed to indicate a low oil level.Use the
dipstick to check the oil level. For additional in-
formation, refer to “Engine oil” in the “Mainte-
nance and do-it-yourself” section of this manual.
CAUTION
Running the engine with the engine oil
pressure warning light on could cause se-
rious damage to the engine almost imme-
diately. Such damage is not covered by
warranty. Turn off the engine as soon as it
is safe to do so.
High temperature warning light
When the ignition switch is placed in the ON
position, the high temperature warning light illu-
minates and then turns off. This indicates that the
high temperature sensor in the engine coolant
system is operational.
CAUTION
If the high temperature warning light illu-
minates while the engine is running, it
may indicate the engine temperature is
extremely high. Stop the vehicle safely as
soon as possible. If the vehicle is over-
heated, continuing vehicle operation may
seriously damage the engine. For addi-
tional information, refer to “If your vehicle
overheats” in the “In case of emergency”
section.
Pure Drive Hybrid™ warning
light
When the ignition switch is in the “ON” position,
the hybrid system warning light illuminates. After
starting the hybrid system, the hybrid system
warning light turns off.
If the hybrid system warning light illuminates
while driving, it may indicate that there is a mal-
function in the electric motor and/or other hyrbrid
system components.
Stop your vehicle immediately and contact an
NISSAN dealer.
Low tire pressure warning light
Your vehicle is equipped with a TPMS that moni-
tors the tire pressure of all tires except the spare.
The low tire pressure warning light warns of low
tire pressure or indicates that the TPMS is not
functioning properly.
After the ignition switch is placed in the ON
position, this light illuminates for about 1 second
and turns off.
Low tire pressure warning:
If the vehicle is being driven with low tire
pressure, the warning light will illuminate.
A “Tire Press Low - Add Air” warning also
appears in the vehicle information display.
2-12Instruments and controls

If the hill descent control switch is on and the
indicator light blinks, the system is not engaged.
If the indicator light does not come on when the
hill descent switch is on, the system may not be
functioning properly. Have the system checked
by a NISSAN dealer.
For additional information, refer to “Hill descent
control system on indicator light” in this section
and “Hill descent control system” in the “Starting
and driving” section of this manual.
Low temperature indicator
light (blue)
The low temperature indicator light illuminates
when the engine coolant temperature is low.
When the ignition switch is placed in the ON
position, the low temperature indicator light illu-
minates and then turns off after the engine cool-
ant has warmed up.
If the low temperature indicator light stays illumi-
nated after the engine has sufficiently warmed
up, it may indicate the low temperature sensor in
the engine coolant system is not functioning
properly and may need servicing. Have the sys-
tem checked, and if necessary repaired, by a
NISSAN dealer promptly.
Malfunction Indicator Light
(MIL)
If this indicator light comes on steady or blinks
while the engine is running, it may indicate a
potential emission control malfunction.
The MIL may also come on steady if the fuel-filler
cap is loose or missing, or if the vehicle runs out
of fuel. Check to make sure the fuel-filler cap is
installed and closed tightly, and that the vehicle
has at least 3 gallons (11.4 liters) of fuel in the
fuel tank.
After a few driving trips, the
light should
turn off if no other potential emission control
system malfunction exists.
If this indicator light comes on steady for 20 sec-
onds and then blinks for 10 seconds when the
engine is not running, it indicates that the vehicle
is not ready for an emission control system
inspection/maintenance test. For additional infor-
mation, refer to “Readiness for
inspection/maintenance (I/M) test” in the “Tech-
nical and consumer information” section of this
manual.Operation
The MIL will come on in one of two ways:
●MIL on steady — An emission control system
malfunction has been detected. Check the
fuel-filler cap if the LOOSE FUEL CAP
warning appears in the vehicle information
display. If the fuel-filler cap is loose or miss-
ing, tighten or install the cap and continue to
drive the vehicle. The
light should turn
off after a few driving trips. If the
light
does not turn off after a few driving trips,
have the vehicle inspected by a NISSAN
dealer. You do not need to have your vehicle
towed to the dealer.
●MIL blinking — An engine misfire has been
detected which may damage the emission
control system. To reduce or avoid emission
control system damage:
– do not drive at speeds above 45 MPH
(72 km/h).
– avoid hard acceleration or deceleration.
– avoid steep uphill grades.
– if possible, reduce the amount of cargo
being hauled or towed.
